LOOSE-LEAF BINDER.

Application led September 10, 1924. Serial No. 736,858.

One of the objects of this invention is to devise a novel construction of a loose leaf binder which consists ot' only two parts. Each part is` preferably formed roman integral piece ot material, one part being formed from sheet material and the other part can be formed from sheet material or from a wire.

Another object of this invention is to devise a loose leaf binder which can be very cheaply manufactured.

With the Jioregoing and other obJects 1n viewas will hereinafter more clearly appear, my invention comprehends a novel construction and arrangement of a loose leaf binder.

lt further comprehends a novel construction ot a binder, the holder of which is of novel construction, being formed from an integral piece ot' sheet material, and the tiller-holding member is also of novel construction and has means to co-operate with the holder to ed'ect the locking `or unlocking of such member.

Other novel features of construction and advantage will hereinafter more clearly appear in the detailed description and the appended claims.

For the purpose of illustrating the 1nvention, l have shown in the accompanying drawing a typical embodiment of it, which, in practice, will give reliable and satisfactory results. It is, however, to be understood that this embodiment is typical only and that the various instrumentalitiesot which my invention consists can be variously arranged and organized, and that the invention is not limited to the precise arrangement and organization of these instrumentalities as herein set forth.

Figure 1 is a plan view of a memorandum book in conjunction with which a loose lea]c binder embodying my invention is employed.

Figure 2 is a plan view, on an enlarged scale, of a ortion of the binder.

Figure 3 1s a plan view similar to Figure 2 but showing the parts in a diierent relation to each other.

lEigure 4 is a plan view, on an enlarged scale, of the fixed portion of the binder.

Figure 5 is a section on line 5--5 ot' Figure 1.

Figure 6 is a section on line 6 6 of igure 2.

Figures 7 8 and 9 are perspectlve views of different forms of filler carrying members, embodying my invention.

.Figure 1() is a sectional view of a loose leaf binder embodying my invention, with the filler carryin member seen in Figure 9.

rlhe fixed bin er part 2 is formed from a single sheet of material and preferably from metal. It is provided with the bottom 5 which terminates in the upwardly projecting lip 6. The bottom 5 is connected with the top 7 by means ot' the bent portion 8 and the marginal edge portion at the side of the top is bent downwardly and partly around the filler-retaining member 9, as at 10, see Figure 5. The free end portions of the tixed portion 2 are bent` around and pressed against the back of the cover 3 and the free ends pass through apertures 11 in the cover and bottom 5 and are clinched or bent over at 12, the top 7 having openings 13 to permit a suitable tool to be passed therethrough to effect the clinching operation.

The top 7 is provided near one of its marginal edges with a plurality of slots 14, and at its opposite marginal edge with the slots 15 which are enlarged as at 16 and form a locking portion 17. rllhe idler-retaining member 9 may have diderent forms of construction.v ln Figtres 1 to 6 inclusive it consists of a `wire bent to form a desired t number of iiller retaining loops 18 which terminate in inwardly extending hooks 19. Instead of forming the filler-retaining member 9 of wire, it can be formed from sheet material as seen in Figure 8, in which the iller retaining member 2O has the same general conformation as that seen in Figure 7.

lnstead of having the hook at the tree end of the loop, it can extend outwardly from the :filler-retaining member at any desired locations. As shown in Figures 9 and 10, the longitudinal stretch ot the illerretaining member 21 is provided with a laterally extending locking member 22 and the loop terminates in a straight end without a hook. This end extends into an opening 23 in the casing 24 which is of the same formation as the member 7 except that it is provided with the openings 23 and the slot 25 is located to co-operate with the locking member 22.

lt will be clearly understood from the drawings that the fixed part 2 is formed. from an integral sheet of material which is bent so that the filler carrying member is capable of relative longitudinal movement therewith.

The filler is provided in the usual manner with apertures, so that the hooks 19 can be employed to pass therethrough, or if the hook or locking member is in tlie form seen in Figure 8, the free end of the loop can pass therethrough. The filler-'carrying member is then turned downwardly to bring,'for example, the hook 19 into the slots 16 andthe filler-carrying member is then moved forwardly or to the left so that such hooks ass beneath the locking portion 17 of the ed part of the binder. When the filler-carrying member ismoved rearwardly or towards the operator the hooks 19 will pass into thev slots 16 so that the filler-carrying member can be moved outwardl and any desired sheet or sheets of the ler can be inserted or removed.

In the form shown in Figures 9 and 10, the hook 22 has the same function as the hook 19 and in this embodiment of m invention the fixed member is provided witli the open-` ings 22 into which the free ends of the loops of the filler-carrying member extend. These locking members 22 vwhen thc ller carrying member 21 is moved longitudinally in the proper direction lock with the member 24 and prevent the opening of the filler-carrying member.

My present invention can be very economicall manufactured, and the parts are positive y locked together when in locked position.

It will now be apparent that I have devised a new and useful loose leaf binder which embodies the features of advantage enumerated as desirable in the statement of the invention and the above description, and while I have, in the present instance, shown and described a preferred embodiment thereof which will give in practice satisfactory and reliable results, it is to be understood 'that this embodiment is susceptible of modification in various particulars without departing from the 'spirit or sc ope of the invention or sacrificing any of its advantages.

1. A two part loose leaf binder comprising a single sheet of material bent u on 1tself to form a top and a bottom, the ree marginal edge of the bottom being upturned, a filler-cariying member around which the free marginal edge of said top is turned, to hinge said filler carrying member thereto by the said upturned edges and another portion of said sheet, said top having slots therein and said filler-carrying member having hooks movable in said slots, and, when in locked position, locking with the bottom of said top.

2. A loose leaf binder comprising a fixed memberaand a movable member hinged to and having a relative longitudinal movement with respect to said fixed member, said fixed member havino its end portions deiected downwardly, laterally and upwardly and connected thereby to a cover and provided with openings in its top portion to receive a clinching element to clinch said end portions between the top and bottom of said member, said movable member having loops to receive the filler and having hooks which when in one position in said slots are in unlocked position and which when in another position in said slots are in locked position.

3. A two-part loose leaf binder compris- .ing a fixed and a movable member, said fixed member comprising a sheet of material bent upon itself to form a closed top, bottom and sides with the free edge of the botv tom bent `upwardly, said movable member being hinged between said upwardly bent portion and the juxtaposed portions of said fixed member, said movable membe'r being formed of a rod bent upon itself to form double strand hooks, the free ends of which hooks extend laterally inwardly, and said top having at opposite sides slots to'provide for longitudinal sliding movement of said hooks transversely to their planes.
